It was already 9 pm when I returned to the team, and most of them had already left work.

After ordering a few takeaways and filling it out, Xiao Ran and Zhang Lei went to the technical department, while Li Fangfang switched to the lounge. He had a duty tonight.

Naturally, there will be no one in the technical department that works overtime all year round. The audio-visual laboratory is still checking the surveillance of Chen Ang’s residence and Ruan He’s community, and supplementing evidence as much as possible.

As for the surveillance screen around Chen Ang’s store, it is relatively useless, and no one cares about it for the time being after being transferred.

However, from the perspective of Xiao Ran and Zhang Lei, the significance of these surveillance is much more important. After all, their current target is Ruan He, not Chen Ang.

Zhang Lei is coming to the relevant surveillance. After the partition is divided, Xiao Ran said: "I go from front to back, you go from back to front, and focus on the 29th of last month. After all, the memory card was taken that day."

Zhang Lei made an ok sign, and Xiao Ran also sat down and started to look at the surveillance in Chen Ang’s store on December 1st as early as the earliest.

Generally, the surveillance in shops cannot be found by surveillance one month ago. For example, a milk tea shop around a cosmetics store has external cameras, but due to the small storage and high surveillance pixels, it can only see the surveillance content within half a month.

Chen Ang used a large-capacity hard drive in the store, and the content that can be recorded is naturally relatively extended, just one can see the situation in the store a month ago.

However, Chen Ang used an ordinary camera in the store, and he could only see the situation inside the store. The situation on the roadside in front of the store is in a surveillance corner and cannot be seen. Fortunately, the road camera on Wufang Road can see the picture in front of the store. Although the distance is far, you can basically see it after sharpening.

According to Chen Ang, Ruan He first went to his store to buy cosmetics at the beginning of last month. I can’t remember the specific time, it was about 1 or 2.

As for the inquiry record of Ruan He as an eyewitness, when the investigator mentioned this issue, Ruan He also said something unknown and did not give accurate time.

The picture on the display is changing rapidly, and time in reality is passing by bit by bit. Before I knew it, it was approaching zero. Only Xiao Ran and Zhang Lei were left in the huge audio-visual laboratory, with their sour eyes open and paying attention to the doubts that might pop up in the picture.

Xiao Ran has finished the store and road surveillance for the first three days of last month, but there was no sign of Ruan He. Obviously, what Chen Ang said was not accurate.

It was not until 5:20 pm on the 4th that Ruan He's figure appeared on Wufang Road for the first time.

In the picture, Ruan He got out of the car wearing a white coat and holding a handbag. Although his facial expression was uncheckable, he naturally walked into Chen Ang's shop.

This was the situation on the way, and then the scene where Ruan He's back appeared in Chen Ang's store. From the surveillance, you can see that Chen Ang was sitting in front of the counter and looking down at his mobile phone. There were not many customers in the store. A shopping guide saw Ruan He come in and greeted him.

The shopping guide smiled and said a few words to Ruan He, then turned around and knocked on the glass counter in front of Chen Ang.

Chen Ang then looked up. When he saw Ruan He, he was obviously stunned for a few seconds. Then he stood up with a smile, communicated with Ruan He for a few words, and then took Ruan He to the storage room behind the counter.

Xiao Ran is unknown, but from Chen Ang's expression at the first time and the subsequent explanations of Chen Ang, it can be inferred that this should be the first contact between Chen Ang and Ruan He.

After about seven or eight minutes, Ruan He followed Chen Ang out of the storage room with a box of ‘c’ mask. Ruan He had a beautiful makeup in the picture, but Xiao Ran’s eyes tightened and he paused the video.

Xiao Ran partially enlarged Ruan He's face. After a closer look, Ruan He's makeup at this time was still different from her subsequent makeup. Although she had the shadow of a good face, it was not as similar as before.

Could it be that Ruan He's makeup is gradually moving closer to Zhang Hao? If so, what is the purpose of her doing this?

Before Zhang Hao arrived, was it the first to evoke the suppressed sinful thoughts in Chen Ang's heart, so that when Zhang Hao arrived, Chen Ang completely strengthened his determination to commit crime? Or gradually change his makeup and will not appear so abrupt, avoiding the attention of people around him and thus leaving flaws?

It seems possible that it is reasonable to lay the groundwork in advance with his meticulous scheming.

After Xiao Ran made a mark here, he did not delve into it. After restoring the picture, he was about to continue looking down, but he heard Zhang Lei beside him shouting in surprise: "Look, Xiao Ran, look quickly!"

Xiao Ran moved down his chair and looked at the screen in front of Zhang Lei. The screen showed the road surveillance at around 8 pm on the 29th of last month, the day after Wang Xiaomei was killed.

In the picture frozen by Zhang Lei, a man wearing a military coat holding something was squatting beside the trash can on the roadside in front of Chen Ang’s shop, stretching his right hand to grop under the trash can.

"This is……"

Xiao Ran opened his eyes wide. Although the man was in a relatively dark place in the picture, Xiao Ran recognized the person at a glance with the bright lights in the cosmetics store: it was the uncle who they sent back not long ago, called Laozang!

"This... is the uncle and Ruan He in the same group? Is he pretending to be crazy?"

Zhang Lei also recognized it, but because he was too excited, his thoughts diverged too quickly: "But if he pretended, why did he sit at the door of Chen Ang's store? Are you guarding against us? But seeing where he lives, he doesn't look like a normal person..."

"No, maybe it was someone who asked him to help take away the storage card when he was not confused." Xiao Ran shook his head slightly and said solemnly.

Zhang Lei took a deep breath, but still couldn't suppress the excitement in his heart: "Will the 'someone' you are talking about, Ruan He?

If it was Ruan He, then he would be a witness to Ruan He! As long as he could prove that it was the memory card that Ruan He took from him, we would have reason to act against Ruan He!"

“Look down.”

Xiao Ran asked Zhang Lei to continue playing the surveillance screen. Although the uncle named Lao Zhang was suspected to be an intermittent mental patient, he could still be a witness during his awakening stage. However, who can prove that he has the ability to think when he saw the person who asked him to take the memory card?

The screen continued to play. After the old latch in the surveillance touched the storage card at the bottom of the trash can, he first looked at the front of his eyes for a while, then stood up and walked straight to the path in his residence. The whole process was of course of purpose and no different from that of a normal person.

Judging from the surveillance, Lao Zang should have the ability to think at this time, but the focus is on Lao Zang's uncertainty. The video only captures his personal behavior. Some mentally ill patients also look no different from ordinary people when they are sick.

Surveillance alone is not enough. If you want to establish the identity of Laozang's witness, you also need to find someone who can prove that Laozang was awake at the time.

Or, there is other direct evidence.
